Depending on how the dasd_mod module was loaded, our device could have
already been marked as online or offline. We need to make the sysecho
sensitive to this and not fail if the attribute we're trying to set has
already been set.
Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:
inst_libdir_file "libdevmapper-event-lvm*.so"
